Koni Single Adjustable Front Strut - Koni strut inserts are bolted into your existing strut housings, and are externally adjustable from underneath the hood, even with the factory strut brace. Ground Control Threaded Sleeves This system is designed to eliminate stress risers caused by machining notches into the strut housing. Unlike other companies that claim superiority by cutting threads into a critical component of the suspension, Ground Control uses engineering common sense to maximize the strength of the suspension.
Ground Control Adjustable Spring Perch - A unique design, that uses an allen head bolt to clamp the single threaded perch into the correct position. No secondary pieces are needed to "jam" the threaded perch into position. This method of clamping onto the threads also prevents sand, grit, and water from getting into the threads, which is a common problem with jam nuts.
